A federal judge — fed up with NYCHA’s inability to abate toxic mold in its aging apartments — has agreed to appoint a special master to enforce a two-year-old pact to fix the problem

He's hoping the bottom line will be mightier than the bullet. Sen. Chuck Schumer said Friday he wants the federal government to use its "massive purchasing power" to put the financial screws to gun manufacturers who deal with shady weapon sellers.

After vehement protests helped block the nation’s first smart gun from entering the marketplace, proponents of the technology are gearing up for another fight, intent on capitalizing on renewed interest in gun safety after a spate of high-profile shootings.

After three school shootings in three weeks, the Obama administration is looking at executive orders that would toughen both the sale of and access to guns. Would it work?

Today, shots rang out at Northern Arizona University and Texas Southern University. Thus far, two students have been reported dead and four others wounded. This is the 282nd day of 2015, and the Northern Arizona shooting was the 299th mass shooting of the year in the United States.

The day before President Barack Obama heads to Oregon to meet with families of victims in the community college mass shooting, a group of about 30 clergy and community organizers gathered outside the White House, calling on President Barack Obama to “stop whining” and use his position to achieve gun control without Congress.

When it rains, it pours — right through her ceiling. But the 70-year-old woman, who lives in the King Towers in Harlem, is prepared. The public housing resident has created an elaborate network of aluminum foil aqueducts, taped to the ceiling to channel the deluge into buckets placed strategically on the floor. The jury-rigged funnel system keeps the rainfall off her television, her stove and her 2-year-old son, Josito.

NEARLY three years ago, in the days after the mass killings at Sandy Hook Elementary School, President Obama went to Newtown, Conn., to speak at a vigil for the victims. He spoke movingly, and seemed to embody the nation’s outrage and its determination to reduce the number of people killed with guns in America. “Do not lose heart,” he told the families of the victims. He said he would use “whatever power this office holds.”

Frustrated tenants and advocates rallied outside City Hall Thursday, calling for NYCHA Chairwoman Shola Olatoye to step down.

Mayor de Blasio professes to care about public housing far more than his predecessor did. It is time for him to take ownership over the conditions that plague thousands upon thousands of souls trapped in NYCHA buildings — leaky roofs, moldy bathrooms, unsafe lobbies and filthy elevators. These problems are long-term, sometimes life-threatening, and in many cases getting worse under his watch.

Almost 300,000 New Yorkers are on the waiting list for a spot inside a New York City Housing Authority Building yet hundreds of apartments remain vacant, some for more than 10 years. But NYCHA says vacancy rates are the lowest in a decade and that it can’t make the necessary repairs without the necessary funding.

Jessica Franco Ramos of Bushwick has a daughter who’s excelling at a public charter school — and a younger brother struggling at a traditional district school. Derrick Calder, of the South Bronx, pulled his daughter Jodie out of a public school, IS 318, where fights filled the halls and bullying was rampant. In a Catholic school, she found refuge at a cost of $4,000 a year. Celia Velasquez, a Bronx grandmother, was thrilled to discover that her grandson aced the gifted and talented test — earning admission, at least in theory, to a local program that would challenge him. But District 7, the city’s lowest-performing district, has none. She sends the young boy to a school 40 minutes away.

Carmen Fariña answered questions from parents and educators at a town hall forum Thursday night. Here are a few of the topics covered: Q: “Can we get more counselors to help troubled students in our schools?” — Leton Hall, Bronx, teacher at Mott Hall Science and Technology Academy

Parents, teachers and concerned education advocates packed the room Monday night at a “Fight for Their Future” forum attended by city Schools Chancellor Carmen Fariña. About a half-dozen parents selected by the co-hosts, the Daily News and Metro IAF, a community group, questioned the boss of the nation’s largest school system about the real-life issues families face in the public schools.
